The 2004 murder of Paiche Unyolo is reexamined on tonight's September edition of Crimecall on RTE One and Paiche's sister Lucy comes to Ireland to appeal for information.

Paiche was a 25-year-old mother of two whose remains were discovered at Brenor Bridge, Piltown, Kilkenny on July 23, 2004.

Originally from Malawi, Paiche had been living in Ireland since 1999. She was married with two young children and living in Waterford when she went missing earlier that July.

Paiche's sister Lucy came to Ireland to issue a fresh appeal for information.

Paiche Unyolo went missing in July 2004 and her remains were discovered at Brenor Bridge in Kilkenny on July 23

"It's like 2004, the same feeling," she says on tonight's Crimecall. "How can somebody take a human being and throw her down the river and let her be there? It's lonely, it's cold, it's cold, it's lonely."

She describes Paiche as a "loving girl, a loving sister" and adds, "She used to be the funny one in the family and we used to talk a lot on the phone. She could call me and we could stay hours and hours. She could make me laugh."

Lucy was interviewed on Brenor Bridge where Lucy's decomposed body was found.

"We came to this spot just to see where they found the body, but they told us not to see the body because it was badly decomposed and the head was decapitated so she had no head," reveals Lucy.

"I just need some answers, somebody there who knows what happened to her [and] we just need some answers please. We just need some answers from someone to tell us what happened to her."

Crimecall, hosted once again by Grainne Seoige and Philip Boucher Hayes, also covers the case of Barry Corcoran, a missing person from Wicklow.

Barry (39) was last seen on July 6th to 7th. He had travelled up from Wicklow town where he lived with his brother to visit friends in Dublin city.

CCTV shows Barry at various times throughout the day. He spoke to a friend in Wicklow on his mobile that evening and has not been heard from since. His family and Gardaí are very concerned for his welfare.

Finally, Gardai also appeal for information on a cash in transit robbery at a Maxol service station on the Dublin Road in Navan which took place on August 25 at about 3.25pm.

A cash-in-transit van was targeted when refilling the ATM machine and a raider threatened the security guard and escaped with a quantity of cash.

The car used in the raid a green Honda CR-V was discovered burnt out close to the scene. The cash box was found at around 4:20pm in Bealing View, Tyrellstown, Dublin 15.

Gardai are also seeking the public's help to track down the perpetrators of a robbery with a firearm in Dublin 5, a burglary in Pimlico, Dublin 8, a raid on a service station in Ballinteer, Dublin, an arson attack at Cery's Road in Limerick and criminal damage of an ATM on the Dublin Road in Castleblaney.
